Electrical Connector Ground Sheet Layout for Stronger Mating Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in improving signal transmission quality due to inadequate grounding effects.
Innovation Solution
The electrical connector incorporates a first ground sheet with corrugated grounding elastic arms that protrude into the receiving slot to directly abut against the mating module, providing enhanced grounding by spacing the abutting portions along a direction without direct contact with the module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional grounding structures are used, then the structure is simple, but the grounding effect is insufficient leading to poor signal transmission quality
Solution Approach 1:
The ground sheet is segmented into multiple grounding elastic arms (first grounding elastic arm, second grounding elastic arm, third grounding elastic arm, fourth grounding elastic arm) that are spatially distributed around the signal terminals. Each arm independently contacts the mating module to provide localized grounding points, improving overall grounding effectiveness through distributed segmentation rather than a single centralized ground structure.
Solution Approach 2:
The grounding elastic arms extend in multiple spatial dimensions (first direction perpendicular to second direction) to create a three-dimensional grounding network. This multi-dimensional arrangement provides comprehensive shielding around signal terminals from different directions, enhancing grounding effect by utilizing spatial dimensionality rather than relying on a single-plane ground connection.
2Reliability
If grounding elastic arms directly contact the mating module, then grounding effect is improved, but the structure becomes more complex
Solution Approach 1:
The grounding elastic arms are designed with elastic properties that allow them to dynamically adapt to the mating module during insertion. The arms can flex and deform to ensure reliable contact with the mating module's grounding surfaces, providing consistent grounding pressure and maintaining reliable electrical connection throughout the connector's operational life.
Solution Approach 2:
The grounding elastic arms utilize changes in physical parameters (elastic deformation, contact pressure) to achieve reliable grounding. By allowing the arms to elastically deform and adjust their contact pressure with the mating module, the structure maintains optimal grounding conditions without requiring complex adjustment mechanisms or multiple components.

AI summary
An electrical connector includes a housing, a first terminal module and a first ground sheet. The housing includes a receiving slot for receiving a mating module. The first terminal module includes two first conductive terminals. Each first conductive terminal includes a first contact arm. The first contact arm includes a first contact portion protruding into the receiving slot to mate with the mating module. The first ground sheet includes a first grounding elastic arm. The first grounding elastic arm includes a first abutting portion, a second abutting portion and a first connecting portion. Both the first abutting portion and the second abutting portion at least partially protrude into the receiving slot to be configured to directly abut against the mating module. The first connecting portion does not directly abut against the mating module.
